SHUTTLE AND QUILL FOR NARROW-WARE LOOMS.

SPECIFICATION forming part of Letters Patent NO. 748,887, dated January5, 1904.

Application filed November 9, 1903- $erial No. 180,307. (No model.)

Narrow-Ware Looms, of which the followingdescription, in connection withthe accompanying drawings, is a specification, like letters on thedrawings representing like parts.

My invention aims to improve shuttles and their quills for use in loomsfor weaving tapes and other fabrics to which they may be adapted.

Prior to my invention shuttles for looms of this character have usuallybeen provided with quills of cylindrical formation and having a lengthmuch greater than their diameter and arranged to revolve duringunwinding of the shuttle-thread about axes which are respectivelyparallel with the lines of travel of the shuttles. Shuttle-quills ofthis shape will ordinarily contain thread enough i for less thanone-half days operation of a loom, thus involving waste of time forrenewals in the midst of each working part of a day. Furthermore,because of the relatively great lengths of the quills the threads indrawing therefrom through the single eyes with which the shuttles arerespectively provided are caused to whip laterally back and forththrough considerable distances, resulting in greatly-varying tensionsand also tending to break or snap the threads. My invention overcomesthese objections by providing for quills which are of much greaterdiameter than the lengths thereof, so that they rest flatwise in theshuttles and revolve about axes which are perpendicular to the lines oftravel of the shuttles. Quills so wound will carry in the same sizeshuttles much more and usually twice the length of shuttle-- threads ascompared with the former quills, above referred to, and have the addedadvantage that the threads are drawn off more nearly centrally'throughthe shuttle-eyes at all times. 7

To enable my invention to be understood, I have illustrated oneembodiment thereof in the accompanying drawings, to which reference maybe had.

In the drawings, Figure 1 in top or plan View shows a shuttle equippedwith a quill in accordance with myinvention; Fig. 2, a righthand edgeview of Fig. 1; Fig. 3, a front edge view of Fig. 1, and Figs. 4 and 5details illustrating in cross-section two forms of quills which may beused by my invention.

In the particular embodiment of my invention selected for illustrationherein and shown in the drawings the shuttle a of general semicircularcontour is provided along its straight edge and at one side with a usualraceway a, in which travels the race-block upon the lay. At its oppositeside and also adjacent its straight edge the shuttle is provided with acountersunk rack (1 which meshes with usual drivingpinions also upon thelay and not herein shown. The semicircular edge of the shuttle isthinned gradually from its opposite sides, as best shown at a Fig.2, toapproximate the angular separation of the warpthreads in shed formation,between which the shuttle is required to be reciprocated.

The shuttle is provided with a usual semicircular openingb, and intothis opening extend at opposite sides of the shuttle two resilient orspring-like arms 1), provided at their free ends with facing knobs orprojections 5 adapted to receive and hold rotatively between them thequill-spindle upon which the quill is wound.

The quill may be built up in any suitable cross-sectional form-such, forinstance, as

illustrated in Figs. 4 and 5so long as its diameter greatly exceeds itslength orthickness and so long as the successive windings of the threadare so arranged or traversed one relative to another that the quill orthread mass is rendered self-supporting without requiring the use ofspool heads, ends, or cups for its support. While the quill may berectangular in cross-section, as in Fig. 4, I prefor to build up a quillwhich in cross-section shall show a gradual taper or reduction from aproper point removed from the axis and toward the periphery thereof, sothat when in position in the shuttle, as shown in Figs. 2 and 3, thegeneral shape of the quill will approximate to the taper of the shuttleitself. The quill-spindle 0' may be tubular, as usual,

or otherwise suitably formed to receive the I holding-knobs b in amanner that will permit the quill to revolve as the shuttle-thread isdrawn therefrom. r

The winding of the quill may be accomplished in any suitable manner, asby usual traverse winding means of the universal type or in any othermanner so long as the quills are self-contained and self-supportingwithout the use of opposing cups or holders.

The shuttle is provided with one or more tension members d, which pressupon the periphery of the quill, and also, if desired, with one or moretension members, as d, which press upon the side of the quill, all forthe purpose of placing the quill under desired or necessary tension topreventit from unwinding too easily during reciprocations of the shuttleshould the holding-arms be insufficient for this purpose.

If desired,suitable guide or protection wires e may be provided spanningthe-exposed portions of the quill at opposed sides of the shuttle nearthe thin edge thereof for the purpose of separating the warp-threads orpreventing the latter from coming into too fir-m frictional contact withthe quill during passage of the shuttle through the shed.

A quill built up as hereinbefore described and of which the best examplethereof now known to me is herein shown and particularlydescribed-namely, with a diameter which greatly exceeds its length orthickness-will contain about twice the length of thread as compared withthe present quills, which have a length greatly in excess of thediameter and where its diameter is of the thickness of the shuttle, asis the thickness or length of the quill in my present invention. ThusWithout increasing the thickness of the shuttle I substan tially doublethe length of time during which the shuttle will operate withoutrequiring stoppage for renewal of the quill first.

Furthermore, with my present invention the lateral traverse of theshuttle-thread in traveling from edge to edge of the quill is hardlyone-third of the length of traverse from edge to edge of the quills asat present used, so that the draft of thread is much more direct,permitting much more uniform tension and greater freedom from breakagesdue to twitching or whipping of the thread.

Myinvention is not limited to the particular embodiment thereof hereshown and described, but may be varied within the spirit and scope ofthe invention gathered from the claims.

I claim 1. A shuttle provided with means to hold a self-supporting quillwith its axis perpendicular to the line of travel of the shuttle.

2. A fiat shuttle provided with means for holding flatwise therein afiat self-supporting quill of a diameter greatly in excess of its depthor thickness.

3. A narrow-ware shuttle provided with a quill-opening and quill-holdingfingers projecting thereinto constructed to embrace between them andsupport a self-supporting quill and arranged with their quill-holdingportions opposed to each other in a line perpendicular to the line oftravel of the shuttle.

4. A fiat narrow-ware shuttle provided with means for holding a fiatself-supporting quill flatwise in said shuttle and quill tension meansadapted to press directly upon the thread mass.

5. A flat narrow-ware shuttle provided with means for holding a flatself-supporting quill flatwise in said shuttle and quill tension meansadapted to press directly upon the periphery, of the thread mass.

6. A flat narrow-ware sh uttle provided with means for-holding a flatself-supporting quill flatwise in said shuttle and quill tension meansadapted to press directly upon the flat side of the thread mass.

7. The combination with a flat shuttle made tapering toward one edgethereof, and adapted to hold a fiat self-supporting quill arrangedflatwise with and in said shuttle and also made tapering toward itsperiphery.

8. A shuttle provided with means for holding a fiat self-supportingquill flatwise in said shuttle and quill-protecting means spanning thesaid quill or a portion thereof.

9. A narrow-ware shuttle having an opening therethrough, means toconfine in both directions in said opening a self-supporting quill withits axis perpendicular to the line of travel of the shuttle, and shuttleguiding and driving means arranged at one side of said opening.

10. A narrow-ware shuttle having an opening therethrough, means toconfine in both directions in said opening a self-supporting quill withits axis perpendicular to the line of travel of the shuttle, shuttleguiding and driving means arranged at one side of said opening, andprotection means spanning said opening adjacent the edge of the shuttleopposite the driving and guiding means.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
